Abstract :
Have you ever tried to explain some aspect of your design and not known where to start? Perhaps you had to present how you solved a problem or justify your chosen design among several alternatives, and you weren\´t sure how to highlight key design aspects critical in achieving a certain requirement. Design decisions with widespread impact or design nuances that might confuse new team members can benefit from good definitions and narrative explanations. When fellow designers repeatedly ask, "why did you do it that way?" It\´s good to have an effective presentation that explains the tricky parts of your design without losing people in the details
